#bitcoin cold storage levels. More security adds more complexity. Most people are fine with level 2 or 3:

1. Open Source hardware wallet with paper backup

2. Open source HWW with steel backup

3. Open source HWW with steel backup and passphrase

4. 2 of 3 Multisig using open source multi-vendor HWW with BSMS file and steel backup spread out in the same country

5. 3 of 5 Multisig connected to your own node using open source multi-vendor HWW with steel backup and BSMS file that are spread out over 5 different countries

6. Same as 5, but with a passphrase on each key

I rely think that a passphrase is a non-negotiable in all of these cases. It's a simple level of security that closes so many attack angles.

I wouldn't use a passphrass with multisig unless you are on team never-spend.

I would use lightning if I wanted spendable coins

I think in most cases 6 is adding unnecessary complexity, based on the high security achieved in #5.
